Kipawa syenitic complex is typically enriched in heavy rare earth elements, Zirconium, and, in places, other rare metals are found, such as Niobium. |
Of far less importance are occurrences in gneisses and amphibolites, in small plutons derived from syenitic and gabbroic magmas, and in certain contact-metamorphic rocks. |
Several pools of syenitic magma were separated from the main body of the melt. |
During the early Gardar period, around 1350 Ma, basaltic lavas were erupted and syenitic plutons were emplaced. |
Carbonatites are plutonic rocks from great depth and occur with syenitic intrusions and amongst more exotic minerals can also carry copper-silver and gold. |
In the central part of the intrusion, some small granitic aplite dykes intrude the syenitic rocks. |
